BUTTON.

SPECIFICATION forming part of Letters Patent No. 779,283, dated January3, 1905.

Application filed June 25, 1904:. Serial No. 214,148.

To all whom, it may concern:

Be it known that I, JEREMIAH HoRAN, a citi- Zen of the United States,residing at VVashington, in the District of Columbia, have invented newand useful Improvements in Buttons, of which the following is aspecification.

This invention relates to improvements in collar, sleeve, or studbuttons, and the object is to provide a two-part button of simpleconstruction the members of which may be readily and convenientlyattached to or detached from each other for insertion in or removal froma garment and which when in contact with each other will not becomeaccidentally disconnected.

With the above object in view the invention consists in the novelfeatures of construction hereinafter fully described, particularlypointed out in the claims, and clearly illustrated by the accompanyingdrawings, in which Figure I is a side elevation of a button constructedin accordance with my invention. Fig. 2 is a sectional view through thebase member and tubular shank carried thereby, showing the head memberattached to the base member; Fig. 3, a side elevation of the head andspring-stem carried thereby, and Fig. 4 a view showing the swivelconnection between the head and spring-stem.

Referring now more particularly to the drawings, 1 designates the basemember, consisting of a base 2, of celluloid or other preferredmaterial, having a central opening in which a tubular shank 3 issecured, and formed in its outer face with a concaved recess 4 in linewith the shank. The shank is formed with a shoulder 5 at the inner faceof the base or disk 2, and its end is turned back to form a shoulder 6,fitting into a depression in the base, thus securing the shank firmly tothe disk or base. Said shank is formed tapering inside from end to end,the smaller diameter being at the inner or disk end of the shank. At theouter end of the shank an exterior shoulder 7 is formed.

8 designates the head member, which consists of a stem 9, split to formspring members 10, upon the exterior of each of which, at one 5 en d ofthe stem, ashoulder or lug 11 is formed by preferably turning down thematerial of which the stem is constructed. At the opposite end of thestem a setting 12 of any approved form is revolubly attached, said stemhaving a reduced portion 13 to fit in a central opening formed in thehead, the end of the stem being headed, as at 14, which head 14: fits ina countersink formed in the setting or button-head 12.

In operation to connect the two members of the button the stem isinserted in the shank and moved inwardly therein, the inclined ortapered interior wall of the latter causing the spring members to becontracted or compressed until they pass beyond the inner end of theshank, when they again expand, the locking-lugs 11 engaging the end ofthe shank and holding the base and head members together. By providing atapered or inclined inner wall for the shank, extending from end to endthereof, the spring members of the stem are gradually contracted, sothat the inward movement of the stem may be easily and readily elfected,and the spring members are not subjected to a sudden compression orcontraction, as would be the case were a shoulder or projection providedsimply at the inner end of the shank for effecting the result. Theprojecting shoulder 7 at the outer end of the shank serves to preventthe straddling of the shank by the spring members of the stem when thelatter is inserted in the shank, the shoulder being of greater widththan the space between the spring members. Thus by preventing thestraddling of the outer end of the shank by the spring members the useris saved annoyance and the liability of bending or breaking of thespring members obviated. By forming the'locking lugs or projections uponthe exterior of the stem by reducing the diameter of the latter insteadof forming lugs by compressing the metal of the stem a much strongerstructure is provided. Also by swiveling the head or setting 12 to thestem it may rotate thereon, and should it catch in anything thisrotation will prevent the disconnection of the two members of thebutton.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

ICO

1. A two-part button or stud comprising a base member, consisting of abase and a tubular shank having its interior wall tapered from end toend thereof with its smallest diameter at its inner end, and a headmember consisting of a head and a stem split to form two portionsadapted to be inserted in said shank at the outer end thereof and toengage over the inner end of the shank.

2. A two-part button or stud comprising a base member, consisting of abase and a tubular shank having its inner wall tapered from end to endthereof having its smallest diam-
